I'm getting logspam from RTL871X running buster on my OrangePi Plus 2e.

 

I'm not using wifi on this so I guess I could just disable/blacklist rtl871x to stop this?

But is there a better/cleaner way to stop all these log entries?
Or does it indicate something is broken/mis-configured?

 

syslog is showing many many log entries from RTL871X; each minute I get the following sequence:

This look like there are debug flags enabled in this driver for some reason.

Not sure from which WiFi driver this comes.

 

Fun fact: Found a small bug in the system information collector:

[ 10.279598] RTL871X: rtl8189fs vXXX.XXX.24.8_22657.20170607

Probably has been detected as IP address and therefore anonymized.

I guess this change or that (enabled now) causes this. 

Any solution besides disabling the module?
